We love celebrating Halloween here at Instructables and are already starting to prep our own costumes. Every year we send out postcards to all of you to mark our favorite holiday, and we're doing it again this year!

If you'd like to receive a postcard, please leave a comment here by Friday October 11th, and we'll send you an address request through our normal prize claiming system. We're also sending a special prize pack with a limited-edition teeshirt and book to 10 randomly-selected people from the comments below.

Happy Halloween, and we're looking forward to seeing all of your creations!

Au contraire - I am the holder of the massive spreadsheet of addresses for these postcards. We do our best to update, but can only go off of the information you give us. And to thematthatter's point, unless the move is an obvious one, we usually hedge our bets and mail letters to both addresses... just in case there's someone with the same name in a different place.
